Dumpcar body tilter // 2296684

FIELD: transport engineering.

SUBSTANCE: invention relates to devices for mechanized unloading of dumpcars and other vehicles. Proposed dumpcar body tilter has body 3 mounted on lower frame 2 for turning in vertical plane and hinge-coupled with power cylinder 4. Rod 5 of power cylinder is hinge-connected with one end of tie-rod 6 whose other end is hinge-connected to lower frame 2. Said tie-rod has two slots 10 for movement relative to joints fastening to lower frame and to rod. Joint of power cylinder rod and tie-rod is attached to body through slot in body.

EFFECT: increased angle of tilting of body, reduced force acting onto body from side of power cylinder rod.

FIELD: machine building.

SUBSTANCE: invention relates to transport machine building, in particular to dumper platform lifting devices. The proposed dumper platform lifting device incorporates pump (1), oil tank (4), control valve (7), adjusting valve (8) and hydraulic cylinder (9). Bode (10) of adjusting valve (8) represents an adapter (13) attached on hydraulic cylinder (9). Control valve (7) communicates with radial channels (12) in body (10) and stepwise axial channel (11) accommodating plunger (15) that features preset diametre central bore (16), the said plunger being pressed to end face (21) of the said stepwise channel by spring (17) entering central channels (18, 19) of plunger (15) and plug (20) screwed in body (10). The compression force of spring (17) can be adjusted. There are adjusting shims (24) fitted between plug (20) and the body. The loaded platform downing deceleration results from shifting plunger (15), by fluid pressure, into space (27) and ingress of fluid via channels (23).

EFFECT: higher reliability and safety.
